[0022] The utility model will be further described below with reference to the drawings and specific examples

[0023] Examples

[0024] As Figure 1 ,Figure 2 、 Figure 3 、 Figure 4 The utility model provides a technical scheme: including hollow steel body 1, the both sides of hollow steel body 1 are all seted up with recess 2, the inside fixed connection of hollow steel body 1 has X type board 3, and the inside fixed connection of hollow steel body 1 and located X type board 3 both sides has support plate 4.

[0025] In this embodiment, the cold-formed steel is based on the hollow steel body 1. The hollow design not only ensures the structural strength but also reduces the weight of the steel. The recesses 2 on both sides of the hollow steel body 1 can be used for connecting with other components. Inside the hollow steel body 1, there are X-type plates 3 and support plates 4 located on both sides of the X-type plates 3. The X-type plates 3 can disperse stress to the entire structure when the steel body is subjected to external force, providing support and anti-deformation ability from multiple directions. The support plates 4 on both sides of the X-type plates 3 provide auxiliary support, enhancing the stability of the internal structure and further improving the bending and torsional resistance of the cold-formed steel.

[0026] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The outer side of the X-type plate 3 is equally provided with second through holes 6.

[0027] In this embodiment, the outer side of the X-type plate 3 is equally provided with second through holes 6, which are also designed during the manufacturing process. When the cold-formed steel is in use, the second through holes 6 are not exposed to the external environment due to the presence of the hollow steel body 1 and other internal structures. These through holes can be used for internal structural assembly and reinforcement.

[0028] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The outer side of the support plate 4 is equally provided with first through holes 5.

[0029] In this embodiment, the outer side of the support plate 4 is equally provided with first through holes 5, which are formed during the manufacturing process of the cold-formed steel. The main purpose is to connect and reinforce the internal structure of the cold-formed steel. In actual use, the first through holes 5 are not directly contacted with the external environment due to the wrapping of the hollow steel body 1.

[0030] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The outer surface of the hollow steel body 1 is provided with a corrosion-resistant coating, which is composed of multiple layers of zinc-aluminum-magnesium alloy.

[0031] In this embodiment, the outer surface of the hollow steel body 1 is provided with a corrosion-resistant coating composed of multiple layers of zinc-aluminum-magnesium alloy. The zinc-aluminum-magnesium alloy coating prevents corrosion by forming a dense protective film on the surface of the steel. When the steel is exposed to a humid, corrosive environment, the zinc, aluminum, and magnesium elements in the alloy coating will undergo an electrochemical reaction and be preferentially corroded, thereby protecting the internal steel from erosion. Moreover, the multi-layer composite structure further enhances the protective effect, with each layer of alloy serving as a barrier and protection.

[0032] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , the inside of the hollow steel body 1 is filled with foamed concrete.

[0033] In this embodiment, the inside of the hollow steel body 1 is filled with foamed concrete. After filling, the foamed concrete can tightly combine with the inner wall of the hollow steel body 1. The foamed concrete itself has a certain strength, which plays a supporting and filling role in the steel body, and works together with the X-shaped plate 3 and the supporting plate 4 inside to further enhance the overall strength of the cold-formed steel. At the same time, the characteristics of foamed concrete make it have the functions of heat preservation, sound insulation and fireproofing.

[0034] Working principle:

[0035] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 1 Figure 2 Figure 3 Figure 4As shown, the cold-formed steel is based on a hollow steel body 1 as the basic structure. The hollow design not only ensures a certain structural strength, but also reduces the self-weight of the steel. The grooves 2 on both sides of the hollow steel body 1 can be used for cooperative connection with other components. Inside the hollow steel body 1, an X-shaped plate 3 and support plates 4 located on both sides of the X-shaped plate 3 are fixed. The X-shaped plate 3 can disperse stress to the entire structure when the steel body is subjected to external force through its unique X-shaped cross structure, providing support and anti-deformation capability from multiple directions. The support plates 4 play an auxiliary supporting role on both sides of the X-shaped plate 3, enhancing the stability of the internal structure and further improving the bending and torsional resistance of the cold-formed steel as a whole. Second through holes 6 are equidistantly provided on the outer side of the X-shaped plate 3, which are also designed during the manufacturing process. During the use of the cold-formed steel, the second through holes 6 are not exposed to the external environment due to the presence of the hollow steel body 1 and other internal structures. These through holes can be used for internal structural assembly and reinforcement. First through holes 5 are equidistantly provided on the outer side of the support plates 4, which are formed during the manufacturing process of the cold-formed steel and are mainly used for connection and reinforcement of the internal structure of the cold-formed steel. In actual use, the first through holes 5 will not be in direct contact with the external environment due to the wrapping of the hollow steel body 1. The outer surface of the hollow steel body 1 is provided with a corrosion-resistant coating composed of multiple layers of zinc-aluminum-magnesium alloy. The zinc-aluminum-magnesium alloy coating forms a dense protective film on the surface of the steel to prevent corrosion. When the steel is exposed to a humid and corrosive environment, the zinc, aluminum, and magnesium elements in the alloy coating will undergo an electrochemical reaction, preferentially corroding to protect the internal steel from erosion. Moreover, the multi-layer composite structure further enhances the protective effect, and each layer of alloy can play a certain blocking and protective role. The hollow steel body 1 is filled with foamed concrete. After filling, the foamed concrete can tightly combine with the inner wall of the hollow steel body 1. The foamed concrete itself has a certain strength, which plays a supporting and filling role in the steel body, and works together with the X-shaped plate 3 and the support plates 4 inside to further enhance the overall strength of the cold-formed steel. At the same time, the properties of foamed concrete make it have the functions of heat preservation, sound insulation, and fireproofing.
